Pt. 1: A Decade of Memories (第1部 10年の軌跡パレード, Dai 1 Bu 10 Nen no Kiseki Parēdo, Part 1 Ten Years of Parades) is a Gauntlet that was added in Version 11.10.
The Pt. 1: A Decade of Memories Gauntlet contains a total of 20 No Continues stages. After beating three stages, the player must wait for 90 minutes before they may proceed to the next one (30 minutes for one available). The rewards reset with every appearance of the event.
The reason they were changed is likely because their respective stages included Gary Gory.
Because the map starts in 2012 with the release of battle cats in Japan, but the English version itself was released in 2014, on the English release of this map the years of 2019 and 2022 ended up being skipped so that it would end in 2024, the year of the 10th anniversary of the English version, without having to edit the map or create new stages.
Because of regional differences as well as the 2019 and 2022 cut, the english version of the map omits the release of the Battle Cats' gummies and wafers, the TV comercial in celebration of the 8th Anniversary and the Evangelion Collaboration promotional video, including in their place the addition of Legend Tickets, Ultra Talents and Ultra Forms.
Additionally, one of the strangest omissions is a series of cats at the bottom of the map, most containing gags, that were cut from the English version, aside from Meditation Cat at the end wishing for a good 11th year, it is unknown why most of them were cut.
Out of the cats included at the bottom, Hikakin, Cat Student and Cat Giraffe Modoki stand out for being japanese exclusive units, making their omission more understandable, especially Hikakin for being a collab unit with a japanese youtuber that is largely unknown outside of japan and Cat Giraffe Modoki for being a collab with the Japanese Racing Association.
